Specification of Letters Patent.

Patented Jan. 13, 1914.

Application filed May 20, 1913. Serial No. 768,777. c

nary railway car and connected with the brake mechanism therefor, and which may be easily and quickly operated to securely apply the brakes and to retain the brakes in their applied position at the minimum amount of physical exertion.

It is a further object of the invention to provide a brake operating means wherein the ordinary chain winding upon a drum which is rotated by the brake shaft and wheel and Which is controlled by the customary pawl and ratchet wheel shall be dispensed with, and the liability to accidents from such construction resulting from the breaking of the chain, etc., shall be entirely and effectively overcome.

A still further object of the invention is the provision of means whereby a direct longitudinal movement is obtained so that the brakes are uniformly and simultaneously brought into contact with the treads of the wheels, the halting of one of the wheels previous to the brakes contacting with the remaining wheels and the resultant flat wheels will be effectively prevented.

IVith the above and other objects in view, which will appear as the nature of the invention is more fully disclosed, the improvement resides in the construction, combina tion and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

For the purpose of illustration the accompanying drawings illustrate a satisfactory reduction of my improvement to practice, and in which drawings:

Figure 1 is a side elevation of a car provided with my improved brake operating vmeans, Fig. 2 is a longitudinal sectional View on the line 2-2 of Fig. 1, Fig. 3 is a vertical sectional View on the line 3-3 of Fig. '1, and Fig. 4 is a detail View of the supportlng member or bracket which is connected directly to the car. A 7

Referring now to the drawings in detail, the numeral 1 designates a portion of an ordinary fiat car. Arranged upon this car, centrally of its ends are bracket members, only one being shown in the drawings. The bracket which is designated by the numeral 2 comprises essentially a substantially L shaped member, that is, the said bracket is provided with a vertical arm 3 which is secured to the front of the car and a horizontal arm 4. This arm 4 is secured upon the bottom of the car. At the juncture of the arms 3 and 4:, the bracket is provided with a longitudinal extension 5 and a vertical depending member 6 which has its extremity formed with an angular extension 7 which is arranged in a plane with and directly below the extension 5. The extensions hand 7 will, for the sake of convenience, be hereinafter referred to as shoulders. zontal member 4 is formed with a right angular end flange 8 and a central right angu lar flange 9, each of which extends downwardly from the said member 4:. The shoulders 5 and 7 are provided each with a circular opening, the opening 10 in the shoulder 5 being of a larger area than the opening 11 in the shoulder 7. Passing through these openings is a turning rod 12 which has its upper extremity provided with a hand-wheel 13. The lower end of the rod 12 is formed with a reduced portion or finger 14 which is received within the openings 11, and the shoulder provided between the finger and the rod proper rests upon the upper face of the shoulder 7. The finger 14: is rounded, as is the body of the rod, and the openings 10 and 11 providebearings for the said rod 12.

Arranged upon the lower portion of the rod 12 and disposed between the shoulders 5 and 7 is a sleeve 15 which has its upper end formed with a beveled tooth whe l 16. The sleeve 15 is provided with an opening which is adapted to register with a similar opening in the rod 12 and passing through both of these openings is a securing member in the nature of cotter pin 17.

The member 6 is formed with an enlarged circular opening 18, as is the flange 9, the opening of the flange being designated by the numeral 19. Passing through these The horiopenings 18and 19 is a barrel 20, the outer face of the barrel being integrally formed with a beveled tooth wheel 21 which meshes with the toothed wheel 16 of the sleeve 15. The bore of the barrel is threaded, as at 22, the threads of said bore adapted to co-act with the threaded portion 23 of a rod 21. The rod 24 has a rectangular portion 25, and the end flange 8 of the member 4: is formed with a rectangular opening 26 through which the rectangular portion 25 of the rod 24 extends. The rod 24 has its extremity formed with an eye or opening 27' to which is attached the chain for the brakes.

From the above description, taken in connection with the drawings, it will be noted that when the wheel 13 is rotated the meshing tooth gears 16 and 21 will likewise be rotated, and the rod 24 will travel directly centrally and longitudinally of the car, the exertion in applying the brakes being thus greatly reduced and the pressure of the brakes upon the wheels of the car uniformly applied. I

The simplicity of the device, as well as the advantages thereof will, it is thought, be apparent to those skilled in the art to which such inventions appertain without further detailed description.

Having thus described the invention, what I claim as new is:

In means for applying the brakes to a car, the combination with a car having a centrally arranged L-shaped bracket which is connected centrally to the front and bottom of the car, the bracket being formed with spaced shoulders which extend longitudinally of the car, said bracket being further provided with flanges which are arranged below the car, the shoulders having rounded openings, an operating rod arranged within the openings, a sleeve secured upon the operating rod between the shoulders, said sleeve having one of its ends integrallyforlned with a beveled toothed wheel, a barrel mounted: for rotation in a bearing between the shoulders and in the flange adjacent the shoulders, said barrel having one of its ends integrally formed with an enlarged beveled toothed wheel which meshes with the beveled toothed wheel of the sleeve, the bore of the, barrel being threaded, the second flange of the bracket having a noncircular opening, a non-circular rod passing through the opening, said rod having a threaded extension which is adapted to be engaged within the threaded bore of the barrel, all substantially as and for the purpose set forth. 7

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN W. KEENEY.
